CORRUGATING MACHINE.

n Application filed: November 2, 1922. Serial No. 598,595.

To allzu/wm t may ooncem-f, Y

Be it known that I, J osErH,P.CoNNoR, a citizen of the United States, residing at 'Towsom inthe `county of ,Baltimore andl State of Maryland, have invented new and "useful Improvements in Corrugating Machines,of which the following is a specification.- o

This invention relates to ycorrugatin'g or fluting machines, and particularly to a device for forming longitudinal corrugations in a metal sheet, which is especially adapted for use in the construction of expansion joints. for roads, pavements, and the like One object of the present invention is to provide a machine of simple andy eiiicient construction by which the continuous corrugating of sheets suitable for expansion joints in roadways and pavements ,maybe` produced; rapidly and-at small costofproduction,-the gconstruction being such that the' sheet willfbe deliveredproperly corrugated and-,with its longitudinal margins properly 'smooth .and nishedgso'that the strip will be in condition for handling. Y

A further object ofy he invention is to provide means. whereby. the strip may, if desired, be curved laterally so as to give a strip suitableffor use with roadways and pavements having a crowned or curved sur- '-face. f v .Y

. 4Referring to the drawings, `wherein is shown a preferred yembodiment of my inventiony 1Figure 1 is a view showing the delivery end of the machine.

l Fig..3 is a top plan view.

Fig. 5 is atop plan viewr showing a later-g ally deflected trough for receiving the corrugated sheet.

Fig.` 6 is a view of a sheet after it has issued from the trough shown in Fig.y 5. Y

Fig. 7 is a sectional view of the troughy l showing a cprrugated sheet therein.

Referring to the drawings, like numbers indicating likel parts in the various figures, 10.denotes.a base plate to which` is secured -Ythe'side frames 11, said frames being maine tained in fixed Y position by any suitable means such' as the bolts 12,t as shown.

The lower Vportions of the sideframesll are each provided with stationaryibearings 13 in which is journalled the shaft "14: which carries the lower corrugated roller 15. The

upper kportion of the said frame 11 is provided with elongated recesses 16 which act i as guideways Vfor theV bearing blocks 17y that Acarry the shaft k18 on which is mounted the adjustable roll 19. i, For effecting the proper adjustment of the roll 19 relative to the roll l5, set screws 20 are connected to the movable bearing 17 and extend an appreciable distance above the frame' 11y through threaded openings formed therein. It will be seen that the adjustment ofthe rolls is so effected that the in tensity or degree of corrugation imparted to the metal may bel varied, as desired. 5 e

The shaft 14 projects at both ends a, suitable distance beyond the side frames 1=1 and hassecured adjacentone end Vthereof the drivegear 22, which is adapted to be connected to any `suitable ldrive means (not shown), while at thenopposite endof the i shaft 14 there is carried a gear 23, which is in mesh with a corresponding gear 24 on the shaft 18. It will thus be seen that the rolls ously upon rotation of the drive gear 22,

which is preferablyrsecured tothesame shaft as the roll 15.7 v

. The rear endlof each ofthe sideframes 11 is provided with elongated slots 25 to which are adjustably mounted a pair of guide rollers 26 and 27 by means of the clamping bars 28 and 29, that are secured tothe inner and outer faces, respectively, of the side frame yby the `bolts 30.

IThe fiat sheetofmetal is carried from the table'l to the corrugated Lrolls through a pair of L-shaped guide bars 32' which are adjustably attachedto the front ends of the frames 11 by means of the slots 3 3 and screws 341, asfshown. kA similarly shaped .pair ofy guide barsl are adjustably posi- `ingthe metal to and from the corrugated rolls, but also as supports to tie the side frames together. ,y

A The corrugated rolls 15-and 19vfarevrpref- Y or `it may be of curved formation, as shown i Virl-full vlines, and of such length as may be desired.

Where the curved trough is used, the stock issuing from the machine vvill bey curved or *bentlaterally' by the trough so as to produce a sheet` such as is shown in Fig. 6. ,The vcorrugated sheet curved, as shown in Fig. 6,

is designed for use With'a crowned road orr` pavement, and'anydesired curvature may f be given' to it by changing the curvature of` 1 the trough.
